Gas Heat Sequence of Operation

Call for Heat

•

On a call for heat, the thermostat contacts close &

the control board receives 24 VAC on the W terminal.

•

The control board microcomputer runs its self-check

routine.

•

The control verifies the limit switch is closed (24 VAC

on Pin 8 of the 12 Pin connector).

•

The control verifies that pressure switch circuit is

open (0 VAC on Pin 5).

•

The control module performs a gas valve circuitry

check to verify gas valve relay state and presence of

voltage at the valve.

•

The system will energize the Induced draft blower.

• The pre-purge period begins once the pressure

switch is detected closed (24 VAC on Pin 5).

•

After the completion of pre-purge, the control will

energize the igniter.

•

After completion of the ignitor warm-up period:

• The gas valve is energized.
•

The ignitor is de-energized as soon as flame is

sensed.

•

After 30 seconds the indoor blower is energized on

heating speed.

•

When the thermostat is satisfied:

• The gas valve is de-energized.
•

The inducer remains energized for the post purge

period (15 seconds).

•

The indoor blower runs for the selected off delay pe

riod (90 seconds by default, adjustable from 30 – 180

seconds).

Heating Mode Speed Selection

To change the main blower speed in HEATING mode, follow

the following steps:

Press left or right button till LED displays “gA1 “(for

single stage HEATING). Press center button and LED

will display the selected speed number as Fxx (xx:

Blower speed number).

2. The control shall rotate available speed number

every time Left/Right switches are pressed. Table

below shows the available speeds for Low & High

heat mode.

When the center switch is pressed, the current

displayed speed shall be selected, and control shall

apply the newly selected speed in next heating call.

NOTE: Always refer to the Heating Chart to choose

from available heating speeds

Continuous Fan Mode Speed Selection

To change the main blower speed in circulation mode, follow

the following steps:

Press the left or right switch until LED displays “FSd”.

Press the center switch and LED will display the

selected speed number as Fxx (xx: Blower speed

number from 1 to 9). F01 is the default speed for

circulation.

2. The control will rotate available speed number every

time left/right switches are pressed. All 9 speeds are

available for circulation.

When the center switch is pressed, the current

displayed speed will be selected, and control will

immediately apply that speed setting.

Cooling Mode Sequence of Operation

Low Stage Cooling Mode Sequence:

On a call for low stage cooling, the Y/Y1 or Y/Y1 and G ther

mostat contacts close signaling the furnace control board

with 24 VAC on Y/Y1 or Y/Y1 and G terminals.

•

The 7-Segment will display the cool mode:

  

•

The compressor and condenser fan are energized.

•

The circulator fan is energized at low cool speed after

a cool on delay. The electronic air cleaner will also be
energized.

•

After the thermostat is satisfied, the compressor

is de-energized and the Cool Mode Fan Off Delay

period begins.

•

Following the Cool Mode Fan Off Delay period, the

cool circulator and air cleaner relay are de-energized.
